public final class HighLevelEncoder
extends Object
This produces nearly optimal encodings of text into the first-level of
 encoding used by Aztec code.
 It uses a dynamic algorithm.  For each prefix of the string, it determines
 a set of encodings that could lead to this prefix.  We repeatedly add a
 character and generate a new set of optimal encodings until we have read
 through the entire input.
